Server Interface

Server modules are Node.js [modules][nodemods] that receive metrics for StatsD. Each server module should export the following initialization function:

• start(config, callback): This method is invoked from StatsD to initialize and start the server module listening for metrics. It accepts two parameters: config is the parsed config file hash and callback is a function to call with metrics data, when it's available.

  The callback function accepts two parameters: packet contains one or more metrics separated by the \n character, and rinfo contains remote address information.

  The server module should return true from start() to indicate success. A return of false indicates a failure to load the module (missing configuration?) and will cause StatsD to exit.
